Abstract: A system for detecting the direction of movement of an RFID tag along a path comprising two RFID portals, each of said portals being arranged to detect an RFID tag in a respective zone along the path, the zones being arranged to be effectively exclusive of one another, a RFID tag reader having an associated processor and multiple separate ports, each port being connected to one or the other of the portals, the processor being arranged to determine which portal first receives a RFID tag signal or signals and which portal subsequently receives a second signal from the same tag or tags detected by the first signal receiving portal, the processor providing a signal corresponding to a direction of movement, along the path from the first signal receiving portal to the second signal receiving portal.

Abstract: A system and method for monitoring shelf inventory that combines bar code and RFID technologies to permit electronic data entry of item shelf assignments and real time reporting of item removal from display/dispensing storage shelves.

Abstract: In combination, an RFID antenna array, an RFID tag reader, and a power supply, the foregoing components being adapted to be worn or otherwise borne by a person and be operatively connected so that the power supply powers the reader and the reader energizes the antenna array and receives RFID tag signals through the antenna array while the person passes through an area as the person's hands and arms are unencumbered by said components.

Abstract: A system and method for monitoring retail shelf inventory that combines bar code and RFID technologies to permit electronic data entry of retail item shelf assignments and real time reporting of item removal from display/dispensing shelves.

Abstract: An RFID tag monitoring system with multiple reader units each equipped with processing capacity sufficient to enable the unit to operate autonomously under its own command and control as well as to register in its individual memory the identity of all of the items that potentially could be present at any particular time at a zone or zones to which it is assigned as well as the particular zone at which a specific RFID tagged item is found; data compression at the reader units permits timely reporting of inventory to a main computer.
